Hello guys,

I can't completely understand how captive portal authentication with ClearPass Guest works. Could anyone explain in more detail steps 3 to 5 of the below picture?

I have read something about in some point of the process the client sends the credentials directly to ClearPass (skipping NAD), ClearPass replies directly to the client (skipping NAD again) and then client sends the credentials to NAD and then NAD to ClearPass. Also I have read something about ClearPass POST the user credentials to the NAD device? All this sounds very weird to me. Is there any documentation of the entire process? I have only found the following article:
